This is a different expert. I was asked to see if I could help you.
First we have to look at some basics.........
You said there were no misfire codes. Were there any codes at all?
Have you completely verified the firing order. This distributor cap is very confusing because the sequence on the outside is different from the sequence on the inside.
What are you using to interface with the computer?
I can't find an image with the distributor cap order labeled but it looks easy enough to follow the wires on the following pictures.
